Oversleeping, or sleeping more than 9 hours in a 24-hour period, can be caused by various factors and may indicate underlying health issues. Here's what you need to know about excessive sleep and its causes.

• Shift work disrupting natural sleep cycles

3. Illnesses

• Respiratory infections (flu, cold, COVID-19)

4. Sleep Debt

Health Risks of Oversleeping:
